I have installed a messiah 2 pro in my V7 PS2, it is definitely installed correctly because intermittently plays original dvd, dvd backups, dvd movies (with messiah switched off only!) and it always plays all CD's. One minute it would only do original dvd games and then it will only do dvd backups. I was almost certain that the pot settings on the dvd were incorrect so i have tried adjusting it and got different behaviour as a result, i finnally got a setting that does everything and i tried booting the diff formats in quick sucsession and they all worked, apart from you have to switch messiah off to get dvd movies to work! BUT at the same time i have been having this problem where after a few resets and trying different formats, when you do a reset you suddenly get nothing happen! NO Electrons just black screen - while the disc just continually spins. If i take the PS2 apart down to removing cage above motherboard and then reassemble it will work again for a while, then it will do it again! Please someone help, this is basically a good install but something else is wrong. I have exhausted all options i have ever known. p.s. unplugging power does not cure the black screen problem. I have to take it apart!!
